MACHINE FOB ASSEMBLINGBOTTLE GAPS.

Application filed M84728,

vcounty, and State of New York, have invented certain new and useful Improvements in Machines for Assembling Bottle (laps, of whichthe following is a specification, reference being had therein to the accompanying drawings, which form a part thereof.

My invention relates to machines for assemblin bottle caps, and more particularly to a mac ine Which will cement an untreated cork or other similar, resilient disk, to a skirted or cupped metallic shell, and apply a finishing coating to only the exposed surface of the disk.

In the bottle cap art it has long been the practice to cement disks of natural, or bonded granular, cork in metallic cupped shells having either a, plain or, fluted skirt. The cementing medium has either been applied directly between the disk and the metal portion of the shell or to a paper collet treated on both sides with the cementing medium. Various cements have been used, the character of the cement always having been of a nature so that when, heat is ap' plied to the cap simultaneously with the application of pressure upon the disk, a firm bond between the disk and the shell will occur when the critical temperature of the particular cement is such as, to make it adhesive. It was necessary thereafter, to cool the assembled shell, it being immaterial whether this cooling is done While the cap is subjected to pressure or when it is free therefrom. It is old in this art to use a variety of different cements. Some manufacturers'use resinous cements, others casein compounds, and still others albuminous compound, it being necessary to compound With the base of the cement, ingredients to facilitate the rapid drying or setting thereof, While permitting them to remain fluid until applied to the metallic shell. .In some instances the sheet tin from which the shells are, formed are spotted with the cement, viscosity of the cement being neither essential nor desirable.

Albuminous and casein cements have been used for many years in the "production of corks for champagne bottles, and in my present application I lay no claim to the use of any particular cement, since the matter 1921. Serial no. 473,429.

of the adhesive employed is merely one of selection.

The caps assembled in the machine of my invention do not require the employment of an adhesive coated collet, which has heretofore been used primarily because of the likelihood of the porosity of different disks, and the desirability of interposing a gas impervious sheet between same and the top of the shell so as to avoid the possible entrance of gases from a bottle between the disk and the shell Withja resultant development of what is known in the trade as leakers. A

paper collet might be used, however, but

no advantageous results are secured thereby. This result flows from the application of the surface finish tothe disk.

In order to dispense with the "collet, it has been the general practice in this art to apply to all surfacesof the cork disk, a coating of paraffin, which is highly objectionable, in that itinterferes with an effective bonding of the disk to the shell, or requires a special ingredient in the adhesive.

lVit-h the above conditions in. mind, I have produced an automatic machine so constructed that the adhesive or cement will be applied to the top ofvthe shell, a cork disk will be thereafter delivered to the shell, and

a finishing wax composition Will be applied to only the exposed surface of the cork, the completely assembled cap thereafter being delivered to a finishing head, wherein it will be simultaneously subjected to heat and pressure for the purpose of developing a critical temperature in the cement or adhesive and secure a proper bond between the disk and the shell While at the same time spreading the finishing composition and forcing it'into any interstices in the disk.

The machine has large capacity determined by the duration of the treatment of the completely assembled cap in the finish-J;

as to limit the construction of the finishing head are all old and well known in the art and immaterial to the invention, which resides more particularly in combining with mechanisms cagable of these functions, irrespective of their 10 etailed construction, adhesive and finishing compound applying means in a definite relation to these mechanisms and to each other, for the purpose of securing a certain, and completely finished product.

-The invention consists primarily in a machine-for assembling bottleocaps, embodying therein means for'feeding metallic shells, having therein an adhesive or cement responsive to heat, means delivering a cushion disk within said shell and upon the cement therein contained, means adaptedv thereafter to apply a wax composition to the exposed surface of said disk, and means adapted to apply heat and pressure to said disk and said shell after said wax composition has been applied thereto, and in such other novel features ofconstruction and ,combination ofparts as are hereinafter set forth and described, and more particularly pointed out in the claims hereto appended.

Referring to the drawings,

F ig. 2 is a similar, plan view of the machine, omitting the hopper and its delivery chute, and a portion of the finishing head;

Fig. 3 is an enlarged, cross sectional detail view of the cementv adhesive dropper; and

Fig. 4 is a similar view of the wax Like letters refer to like parts throughout the several views.

The embodiment of my invention shown in the drawings is illustrated in connection with an old andvwell known type of bottle cap assembling machineembodyin therein oppositel disposed runways 10, a apted' to receive t e fluted edge of the skirt and. the

' shell, the upper portion of the shell depending between these runways, where it may be engaged by the usual intermittently actuated feed bar 11.

At one end of said tracks is a rotary table 12 upon which the caps are delivered with the skirt presented upwardly, from an ordinary cap feeding mechanism not shown in the drawings but old and well known'in the art. At the other end of saidtracks is a finishing head 13 of the usual and. well known construction, having thereon a sequence of spring-pressed plungers 14 adapted to develop and maintain pressure upon the completed cap through the disk preparatory to the delivery of the cap for cooling purposes. Said head is maintained at the desired temperature by a heating device 15, preferably a burner extending under-- the various plungers 14 to adjacent the delivery point for the caps.

.Each of the plungers 14 is adapted to be engaged by a fixed cam 16 adjacent the delivery point for the caps withthe two fold object of permitting the ejection of a completely assembled cap and'its delivery to a cooling and inspection belt 17, said cam terminating-at the end of the tracks 10 so that with the actuation of said finishing head 13 after the delivery of each cap thereto, the plunger will automatically descend and remain in the lowered position until it reaches the cam 16, at which point the cement will have been brought to the desired critical temperature, be properly diffused about the surfaces of the cap and the disk, and'be in condition to permit the final setting of the adhesive or cement by the removal of the cap from the high temperature zone, and its exposure to atmospheric air about the delivery alt.

Intermediate. the delivery disk 12 and the finishing head 13 is a cork disk feeding mechanism also of old and well known construction, consisting of a tube 18 in which disks are adaptedto vbe automatically stacked by a mechanism not shown, and a reciprocatory plunger 19 adapted to push the lowermost disk from belowsaid tubes and to a position below a reciprocatory' plunger 20 carried by a vertically movable slide 21 mounted in suitable slideways.

The slide 19 is actuated by means of a rocking lever. 22 actuated from a cam 23, which cam also actuates the slide 21. Said cam is carried by a shaft 24: which also applies powerto all other mechanisms in the machine insofar as the assembling of the cap is concerned, as distinguished from the detailed mechanisms of the shell and disk feeding attachments.

The mechanisms heretofore described are those embodied in one type of assembling machine which has been used for some years past, and is shown and described merely as finishing head. The invention contemplates/130 merely some means for feeding the shells in proper position, some means for advancing them so as tosuccessively subjectthem to other mechanisms of the machine, some means for placing the cork disks in the shell under certain conditions with relation to other mechanisms, and some means for ap- A plying heat and pressure to the assembled cap before cooling same, combined with means for supplying a suitable adhesive or cement to the shell before delivering the cushion disk thereto and for applying a finishing compound to the disk after the cork has been so delivered but before the completely assembled cap is subjected to heat and pressure.

Intermediate the disk 12 and the plunger is a vertical slide actuated by means of the cam 26 carried by the shaft 24, and the connecting rod 27 co-operating with said cam by means of the usual strap 28. Carried by said slide is a cylinder 29 having mounted therein a piston 30 carrying an upwardly extended funnel-mouthed tube 31, the lower edge of which engages a stop 32 within the piston. Acting against said piston is a spring 33.encircling the tube 31 and acting between the stop 32 and the piston 30, thus being in a position where the adhesive will not contact therewith and avoiding possibility of retardation o the actuation of the piston, which is undesi able particularly in high speed machines, as a result of the fouling of the spring. I

The tube 31 communicates with the cylinder 29 through orts 34 arranged between the piston 30 and inder, the bottom of the opening in the tube 31- being closed srr as to limit the communication between said said ports 34.

The lower end of the cylinder is provided with a bevelled valve seat 35 about the outlet of the cylinder and adapted to co-operate with a cone shaped valve block 36 carried by the piston 30..

Below the valve block 36 is a hollow stem 37 havingports 38 normally positioned-below the valve seat 35 but sufiiciently closely thereto to place the hollow stem 37 in communication with the cylinder through said openings 38 when the piston-is raised in a manner which will 'be hereinafter referred to, but to close said ports 38 when thevalve is closed. Below and about the discharge end of the I stem 37 is a pad 39 having a flared opening therein, in register with the opening in the stem 37, for directing the adhesive upon. the inner top of the shell or causing the spotting of the shell for a considerable area about its axis. The pad 39 will also, inthe course of use, gradually have accumulated 'onthe surface thereof, a coating oftheadheSive used, which will serve to prevent the delivery of the lower'end of saidcyland the piston to an excess quantity of the adhesive or cement and ultimately secure a Wider diffusion thereof upon the inner top of the shell.

Since a constant agitation of the adhesive reservoir 40 having attached thereto an old and well known type of dropper nozzle 41 which will permit the adhesive to flow by a sequenceof timed drops from the reservoir through the dropper nozzle mechanism 41 into the funnel top of the tube 31.

The dropper attachment associated with the reservoir 4042 is provided with the usual adjustment means for determining the volume of the drops and the frequency thereof and a removable closure plug for filling purposes.

The adhesive or cement used is preferably such as will not require heating in the reservoir, although by providing a suitable dropping mechanism, a. fusible, resinous or other gum cement might be used, although adhesiveor cement having a casein, serum albumen or egg albumen base may also be used and arein fact preferable.

If desired, the ordinary colletdelivery mechanism may 'be substituted for that heretofore described, although I have found in actual practice that the use of this collet is unnecessary with a cap assembled in a machine embodying my present invention.

Intermediate the plunger 20 and the finishing head 13 and closely adjacent the latter so as to be within the high temperature zone of the machine, is a reservoir 42 ."having a dropping attachment 43 of any desired old an Well known construction, which reservoir is adapted to deliver a wax composition, preferably having a base of cerasine wax, to the tubular funnel-mounted extension 44 of a piston 45 mounted in a cylinder 46 supported by the bracket 47 J from the slide 20. The cylinder 46 is provided with a stop ring 48, a spring 49 acting between said stop ring and the piston 45. The bottom end wall of the cylinder is provided with a bevelled seat 50 and the lower face of said p-istonjis provided with a cone valve 51 co-operating therewith. The tubular member 44'has ports therein adjacent and below the piston 45 while the valve 51 is provided with a depending stem 52.

I It will be observed that the outlet ports through the bottom of the cylinders 29 and 46 are normally closed, but that with the descent of these cylinders and the engagement of the pad 39 and the stem 52 with a tion of the .permitting the cement or adhesive to pass from the cylinder 29 into the shell, and the wax surfacing composition to pass from the cylinder 46 upon the cork disk, while thecylinders are in their lowermost-position, and cause a forcible ejection of some of said materials from] the cylinders during a por-' period during which said pistons are moving away from the shell.

The delivery belt 17 extends for substantially the entire length of the machine, terminating adjacent the table 12 at which point it is elevated and a transversely extending conveyer belt 53 is passed thereunder, the completed caps being directed uponsaid transverse belt by the laterally pitched transfer plate 54. Extending parallel with the belt 17, and below the belt 53, .1

is a wide conveyer belt 55 to'which the completed caps pass in groups along a slide 56, instead of one at a time as in their progress with the belts 17 and 53, said cap-s being removed from the belt 53 and delivered to said slide by a rotary wiper 57 so timed in its movements as to remove the caps from'the belt 53 when a predetermined number of caps are on the belt 53 in the path of the wiper.

The operation of the herein described. ma-

' ways 10, and comes to rest in axlal alinement chine is substantially as follows With each cycle of the machine a metallic capis transferred from the table 12 to the runway between the tracks 10 and is advanced with a ste by step movement, or intermittently, by t e rack 11 until it reaches the finishing head 13. During the dwell between succeeding feeding movements of said rack, an adhesive or cement will be applied to one shell, a cork disk will be fed to another shell intermediate said first named shell and the finishing head, and the wax finishing compound Wlll be applied to the cork disk in a. third shell intermediate the point of delivery of the disk to the shelland the finishing head. During this interval the finishing head will be rotated one step or the distance between succeeding plungers 14; thereon, and a completely finished cap, with the exception of the cooling thereof, will be delivered by saiddelivery head to the delivery and ins ection belt,17, anothercap will be delivere to the transverse conveyer belt 1 53 by the transfer plate 54, and when a sufficient number of caps are upon said last named belt, they will be wiped-therefrom so as to pass over the slide 56 to the wide conveyer belt 55 by which they will be delivered to the packing case, or a counting machine, as desired. The'completed ca s maybe inspected when upon the belt 1 or upon the 60 belt 55, as desired, imperfect caps being removed by the operator.

The length of the belt 17 will afford ample time. for the caps to cool, which cooling is necessary to cause the adhesive or cement to set sufiiciently firmly to form the necessary intimate and lasting bond between the metal of the cap and the inner face of the disk,

belt 53, one cap will be completed and delivered with each cycle of the machine or each rotation of the shaft 24.

It will also be noted that the slides 19, 21 and 25 are all actuated substantially simultaneously, although the cams actuating same may be so set as to give them a slight lead as compared with the rack bar feeding movement, although this is unnecessary, since there will be a 'suflicient dwell between feeding actuations of said rack bar to permit the adhesive or cement, and the cork disk to be properly applied to the shell and the wax finishing compound to be properly applied to the exposed face of the disk;

As a shell progresses along the tracks or with and directly under the cylinder 29, this cylinder will descend and bring the pad 39 into engagement with the inner top of the with the bore of the stem 37. At the same time the sub-atmospheric pressure thus dedeveloped within the cylinder will draw the fluid adhesive or cement from within the tube 31 to below the piston, this cement flowing by gravity through the ports 38, stem 37 and pad 39 onto the central portion of the shell. The rounded top of the shell will expose a considerable area. thereof belowthe said pad so that with the reversal of movement of the cylinder, the p-ressuredeveloped within the lower part of the cylinder will be vented in (part through the open top of the tube 31 an in partthrough the stem 29, thus tending to procure a greater diffusion of the.

adhesive or cement about the shell. Prior to the next actuation of the rack bar 11, the cylinder 29 will be elevated so as to permit the spring 33'to move the piston shell upon shell so that the continued descent of said naeaaie After receiving the cork or cork composition dsk, the shell will be brought directly beneath. the cylinder is which, as the cap comes to rest, will descend and have the control of the cam l6', the temperature of the assembled cap while under pressure being raised by the heater 15 while it is progressing about the finishing head.

The subjecting of the assembled cap to heat will have the effect of causing a uni-.

form wax film to be formed upon the eX-. posed surface of the cork or cork composition disk, except in the event of small voids in said surface which will be filledby the Wax, thus giving a smooth uniform surface to the disk and closing anypores through Y which gas from the charged liquid contents of a bottle can pass to between the disk and the inner top of the shell,

At the same time, the application of heat and pressure will have the effect of causing the desired intimate relation between the inner top of the shell and the adjacent surface of the disk, so that when the critical temperature of the cement or adhesive is reached, these parts will be closely associated, thus not only securing a thorough difi'uson of the cement or adhesive, but assuring the desired intimacy in the bond se cured thereby. T his practice is old and well known in the arts, it being necessary to the securing of a proper joinder of any materials by means of a cement or adhesive;

As the completely assembled cap leaves the finishing head, and is removed "therefrom and deposited upon the belt-17, the cement will be incompletely set, although a subsequent exposure-to atmospheric air will permit its cooling to a point where it will be set, becoming 'sufiiciently hardened to make the separation of the disk from. the shell practically impossible without mutilation of the former.

Since with the selection of a suitable adhesive or cement the time required to complete a cap in the finishing head will be between ten and twelve seconds, it will be appreciated that the machine of my invention may be operated at high speeds.

.VVhile the machine is in operation, the adhesive or cement and also the wax composidisk to pressure so as to secure the OT: diffusion, and penetration of the a tion will flow continuously from the reservoirs 40 and 42 respectively, falling drop by drop-into the funnel-shaped top of the tubes 31 and 44, each drop being divided by the mechanism associated with said tubes to secure the proper quantity of the adhesive or cement and of the wax composition in each shell or upon each disk.

The fixed relation of the said reservoirs not only prevents undesirable agitation ot the fluid therein contained, but will permit the convenient refilling of these reservoirs from time to time, and thus avoid the necessity for the storage or" an excessive volume of these materials which might result in their deterioration or=difliculty in securing a proper fiowthereoi for the purposes of the machine.

I would not be understood as intimating that viscosity is essential to the adhesive or cement after it is applied 'to the shell, being possible to spot the tin sheets from which shells are formed, with this cement, and permit it to stand for a reasonable length of time, the coating thereof being so thin that it will not interfere with the operation' of the punch presses in forming the shells from the sheets; The application of heat to practically all cements of the nature herein referred to, whether fusible or nonfusible, causes reactions which at a certain critical temperature will make them adhesive.

Of course if the adhesive be applied to the shell before it is delivered to the ma iurposes The use ofthe wax finishing compound particularly desirable when the caps contain composition cork disks, although it may be advantageous to'he used with natural cork disks.

it is not my intention. to limit the invention to the detailed mechanismsahout t machine apart from that arrangement or 11 combination of parts by which the. was compound is applied to one surface or the di t before subjecting the assembled shell properreaction of other ingredi compound, to secure gas and liqui i meability about interstices of the dis" impart a better finish thereto.-
